On a dark weeknight in November, where do you go to be around other people without ordering a drink? In Boulder, a sauna club is becoming a more common answer. Boulder Reporting Lab counted three new clubs opening within a month and expected the city to have at least five dedicated social sauna clubs by mid-November, along with mobile saunas and a growing list of spas offering contrast therapy.
All of these places sell the same basic thing: heat, a cold plunge and roughly an hour to move between them. They charge almost the same for it, too. Once the drop-in prices sit side by side, the decision comes down to what each owner built around the sauna and when the doors are open.
A session costs about the same everywhere
Here are the rates each business posts on its own site:
| Club | Location | Drop-in | Session format | 8-visit pack, per visit |
|---|---|---|---|---|
| Berner Collective | 2150 Pearl St. | $35 | Timed one-hour session, up to 15 guests | $27 |
| eversky | 4730 Broadway, NoBo Arts District | $30 | Reserve an hour; drop-ins welcome | $22.50 |
| Third Space & Co. | 2480 49th St., Unit E | $30 | One-hour sauna or two-hour Social Session | about $21 |
| Rekindle Wood-Fired Sauna | Pop-ups in Louisville | $35 per seat | 50-minute slot | No membership |
A single visit costs $30 to $35 at all four. The gaps show up in the memberships, where the cheapest drop-in doesn't lead to the cheapest month. Berner Collective's Sauna Unlimited plan is $129 a month, so it costs less than drop-ins by the fourth visit. eversky's unlimited membership is $155 a month against a $30 drop-in, so it pays off on the sixth visit. Third Space & Co. charges $125 every four weeks for Full Unlimited, which comes out ahead on the fifth visit. It also offers a $7 first week, the cheapest way into any club on this list. eversky's version of a trial is a $20 first visit, and Rekindle lets a first-timer bring a friend for $35 total.
The room around the sauna is the real choice
The owners talked about this openly. Speaking to Boulder Reporting Lab, eversky founder Jamie Jennings compared the clubs to restaurants, "where they each have their own flavor, and you get to see each owner's preferences bleed through." Nuvania owner Will Gensburg told the same outlet there are far more "sauna-curious" people out there than customers the clubs would have to "snipe from one another."
Each club has built its extra for a different part of the day:
Berner Collective works as a coffee shop first. It sits inside a renovated church on west Pearl, and the stained glass in the coffee shop dates to the original 1904 building. Berner Collective pairs two wood-fired saunas and three cold plunges with a public coffee shop serving locally roasted coffee and fresh-pressed juice, plus a yoga studio. A $199 Berner Unlimited membership sits above the sauna-only plan.
eversky is the place for a long afternoon. Its listening room is modeled on a Japanese jazz kissa, a coffee shop or bar built around jazz records, and it's designed for working, reading, talking and listening. Abstract paintings by local artist Danielle Sabathier hang on the walls. The main event is a large Finnish-style sauna with ice baths at different temperatures. Hot drinks in the lounge are complimentary.
Third Space & Co. is built for evenings out. Matt Radford opened it in September 2025 in a converted warehouse in east Boulder. It has four saunas, three cold plunges and a lounge bar that serves mocktails, kombucha and electrolytes. The name nods to the sociologist Ray Oldenburg's idea of a "third place," a gathering spot that is neither home nor work.
Nuvania is built for groups. It's set to open to the public Nov. 15 at 1965 33rd St., Suite B, near The Spot Climbing Gym. It has a 15-person traditional sauna, an infrared sauna for 8 to 12 guests, a group plunge for up to 12, a one-person plunge, a red-light room and a lounge. According to Boulder Reporting Lab, the infrared benches can come out to make room for six-person hot yoga classes, and the club plans breathwork sessions and aufgoss, a European ritual in which an attendant waves towels to move hot, scented air.
Radford's explanation of the whole trend, as quoted by Boulder Reporting Lab, is the clearest statement of what these rooms are competing with:
"You don't have to go out to a bar on a Friday night to connect with people."
In winter, opening hours narrow the choice
In November, with the sun down before dinner, opening times rule out more options than any amenity does.
For a session before work, Berner Collective opens at 7 a.m. daily except Tuesday, when it opens at 1 p.m. after a deep clean. Third Space & Co. runs a 7 to 9 a.m. window on weekdays, then reopens at 11 a.m. Nuvania's launch schedule opens at 7 a.m. on Tuesdays, Thursdays and Saturdays.
Third Space stays open latest, until 10 p.m. Monday through Saturday and 9 p.m. on Sunday. Berner closes at 9 p.m. every day. Nuvania closes at 8 p.m. on weekdays and 7 p.m. on weekends, and its Mondays are reserved for private events.
A few rules matter more than they first appear:
- Age. eversky, Nuvania and Third Space & Co. are all 18 and older.
- Childcare. Nuvania lists a "Little Loungers" program on Tuesdays and Thursdays from 9 a.m. to 3 p.m.
- A women-only hour. eversky holds a women-only bathhouse session every Wednesday at noon.
- What to wear. Third Space & Co. runs shared, co-ed sessions and requires swimwear. eversky requires a swimsuit or athletic wear. Berner asks guests to bring a swimsuit, a water bottle and a towel.
- How strict the clock is. Berner's sessions are timed hours, and guests are asked to arrive 10 to 15 minutes early. Third Space calls its time slots suggestions rather than strict limits. Nuvania's first-timer guide says a typical session runs about an hour but guests aren't strictly on the clock.
The next round arrives over the next few weeks
The calendar keeps moving after Nuvania's Nov. 15 opening. Pause Studio at 3390 Valmont Rd. offers a different format: private infrared sauna and contrast-therapy suites booked in 30- or 60-minute sessions, rather than a shared room. A Nov. 5 press release put its opening at Saturday, Dec. 5, with online booking starting Nov. 19, hours from 8 a.m. to 8 p.m. seven days a week, and memberships starting at $149 a month.
For a wood-fired sauna without a membership, Rekindle Wood-Fired Sauna sets up its mobile sauna and cold plunge in Louisville. Its co-founders draw on Russian banya and Japanese onsen traditions. The remaining November dates are:
- Thursday, Nov. 19, at Ironton Distillery, 1303 Empire Road, from 3 to 9 p.m.
- Friday, Nov. 20, at Ironton Distillery, from 3 to 8 p.m.
- Wednesdays, Nov. 18 and 25, at Gravity Brewing, from 5 to 9 p.m.
There are no lockers at the pop-ups, so Rekindle asks guests to bring a swimsuit or activewear, sandals and two towels.
The scene this fall grew out of earlier attempts. Boulder Reporting Lab credits PORTAL Thermaculture with starting the trend in early 2024 with a pop-up behind Sanitas Brewing Co. PORTAL later moved to the NoBo Arts District. The same outlet reports that the city shut down that location and Ember & Ice in May 2026 over permitting and graywater compliance issues, and that owners of the newer clubs say they are committed to meeting health and safety rules. Ember & Ice now lists public sessions at LaVern M. Johnson Park in Lyons and says its Boulder location will reopen "down the line."
